The body 20 of the car is tiltably supported upon the underframe by means of hinges 21 which have been fully and clearly described in our pending application for United States Patent filed September 11, 1924 for dump' car, and serially numbered 737,028.

The body 20 comprises longitudinally disposed sills 22 and 23 and transverse members 24 to all of which the floor 25 may be c secured. This body also comprises stationary end walls 26 and movable side walls or doors 27. which side walls are operated by means which will be fully described in an application for United States patent which is now being prepared and which will be led .in our names. The. side walls or doors are made the subject of a pending application for U. S. patent filed in our names on March'28, 1925, Serial Noj19,021.

Lerares Adjacent eachv of theouter ends of each bolster 3 a member 28 is provided which comprises sides 29 and top 30 which conf nects the sides. This member 28 straddles the bolster and the sides 29 thereof adjacent their lower ends are pivotally connected With the bolster through the medium of'a pin or bolt 31 which passes through the sides 29 and bolster 3. Opposite the pin 31 and located outwardly therefrom' each ofjthesides 29 is provided with a weight 32 which is preferably integral with the side'or may be made separate and be secured thereto. These weights are for the purpose of moving the support to its normal supporting position as will hereinafter be morefully described. The upper surface ofthe top is sloped downwardly and outwardly and is offset at 33. This top be engaged by the lower surface 34 ofa support 35 which is ysecured to the body, such surface conforming to the shape of the upper surface of the top 30 of the support 28.v

Above each of the cylinders 19, the body 2O is provided with a downwardly depending member 36 which is adapted tobeengaged by the end portion 37 of a piston rod 38 mounted on a piston 39 movably mounted in the cylinder 19. .twill be noted that when the body 2O is in its horizontal or righted position the supports 28 and 35 will be in engagement with each other and that the portion. 37 of each piston rod will not be in engagement with the corresponding member 36. When it is desired to tip theV car this portion of one piston `rod will be moved upwardly by fluid' pres-sure, into engagement with the corresponding member 36 as will hereinafter be more fully described.

At intervals throughout the length of the underframe, bearing members 40 are provided in each of which on each side of the longitudinal center line of the underframe a shaft 41 is journalled which shaft is for the purpose of operating the locking mec-hanisms for the supports 28. Each shaft operates the locking mechanisms aty one side of the ear andk each locking lmechanism comprises a lifting link 42 having spaced sides 43 which are provided with slots 44 through which the shaft 41 passes. These sides are connected together at their top by a web 45. The lower end port-ions of the sides 43 overlap the sides of a. locking bar 46 and are pivotally connected therewithgtrhrough. the medium of a pin 47. Thislocking bar extends outwardly beyondthe pin and at its end, adjacent the lifting link 42, is provided with a stop 48 which is adapted to engage witha stop member 49 formed integral with or secured to the. bolster or other rigid partof the underframe. This bar is also provided with an extension 50 which is adapted to overlie and engage the upper surface of the 3() is adapted to i Lerares member 48 to assist in supporting the locking bar in its proper locking position. This locking bar also extends in the opposite direction to the support 28located on the other side of the longitudinal center line o f the car, and at its end is pivotally connected with such support through the medium of a pin 51. Between the sides 43 of the lifting link 42 a locking member 52 is loosely mounted on the shaft 41 and movable relative thereto, such member having a downwardly depending leg 53 the lower end of which is adapted tovengage the upper surface of the locking bar to prevent such bar from being accidentally moved out of engagement with the stop member 49. This member 52 is also provided with a leg 54 which extends outwardly from the shaft 41 and at an angle to the leg 53. This leg 54 is provided with a slot 55 through which a pin 56 passes, the ends of such pin being mounted in a side 43 of the lifting link 42. Adjacent each of the .sides 43 of the link 42, the shaft 41 is provided with levers 57 which adjacent their ends are provided with lugs 58 adapted to engage a notch 59 formed in the adjacent side 43 of the link 42. The levers 57 are both secured to the shaft 41 and are rotatable therewith.

Each of the piston-rods 38 comprises a hollow sleeve part 60, the lower end of which is mounted on the piston 39 and also comprises a part 61 which extends into the hollow portion of the part and at its lower end is pivotally connected therewith by a pin 62 or any other suitable means. rThis part 61 adjacent its lower end is provided with an outwardly extending arm 63, which at its outer end is provided with a weight 64 that will, due to gravity, insure the movement of the part 61 to its proper normal position of rest. The upper end 37 of this part projects some distance out of the part 60 and is so shaped as to operatively engage the member 36 within a curved notch 65 formed in the lower portion thereof. Below its upcylinder 19. This surface is adapted to beY engaged by the end 68 of the member 36, which `end is some distance in advance of the notch 65. Below the portion 66 the partv 60 is provided with a slotted opening 69 through which portion of one of the members 36 is adapt-cd to pass when the car body is dumped to one side.

rThe top portion of each of the parts 60 is provided `with an offset 70 which forms a seat for the lower end of a lever 71 which is pivotally connected with spaced arms 72 se- Y cured to the shaft 41. To the lower end portion of the lever 71 one end of a link 73 is pivotally connected, the opposite end of such link being slidably connected with the bearing member 40 or any other stationary part. Between the arms 72 and at one side of the pivotal connection between such arms and the lever 71, this lever is provided with a weight 74 which, due to gravity, has a tendency to force the lower portion of the lever toward the part 60, the link 73 being adapted to limit the movement of the lever in this direction, thus insuring its proper engagement with the offset 70 of the part 60. The lever 71 and arms 72 are for the purpose of rotating the shaft 41 to operate t-he body supporting and body locking members and their locking means as will hereinafter be fully described.

Tov each of the parts 61 there is pivotally connected one end of a member 75, the opposite end of such member being loosely connected with one of the shafts 41. This member is for the purpose of holding the part 61 in such position, when it is in its raisedposition and out of engagement with the notch 65, that the end portion 37 thereof will be in the path of travel of the notch 65, so that should the part 61 for any reason accidentally remain in its raised position after the car has been dumped to one side, or should the operator again admit pressure into the cylinder after the car has been dumped and force the parts 61 to their raise-d positions, the car body, as it is righted, will not damage the parts 61.

In the present embodiment of the invention there are a pair of cylinders 19 on each side of the center sills of the underframe, the cylinders of each pair being operatively connected together and controlled so that there are mounted fluid pressure suppl-y pipes 76 which extend throughout the length of the car and at their ends are provided with angle fittings 77 which in turn are provided with connections or hose adapted to be connected with similar hose on adjacent cars when a plurality of the same type of cars are coupled together or with thev pressure supply source. Adjacent each end of the car each of the pipes 76 is provided with a stop cock 78. When a single car is to be operated the cocks at one end ofy the car are open while those at the opposite end are closed. When a plurality of coupled cars are to be operated ally of the cocks in the cars are open except the two cocks at `the farthest end of the last car. Between the cocks in each supply pipe a branch pipe 79 is provided which connects the supply pipe 76 and cylinders 19. Adjacent one end of they operate in unison. In the underframeql0 way valves 80, each having ports 81, 82 and 83 which open toward the pipe 76, cylinders 19 and to the atmosphere respectively. These valves each have a rotatable plug 84 adapted to be moved to such a position that the fluid presiure may be conducted from the supply pipe 76 to the cylinders 19 or moved Vto such a position that the fluid pressure in the cylinders may be conducted to the atmosphere through the port 83. To operate the valves 80,;rods 85 and 86 are provided which extend from side to side of the underframe, and are each operatively connected with one of the valves through the medium ofa lever 87 connected with the plug 84 of the valve, and a link 88 which is connected with the lever 87 and one of the rods. Y At their ends these members and 86 are provided with operating handles 89, and intermediate their'ends are slidably mounted in brackets which may be secured to the underframe.

Between each valve 80 and the corresponding cylinders 19 the pipe 7 9 is provided with an automa-tic cut off valve 91, which is adapted to automatically eut off the fluid pressure from the cylinders 19, after the pistons and piston rods thereof have been moved upwardly a predetermined distance.

This cut olf valve 91 comprises a casing 92 having an inlet port 93 which is connected with the portion of the pipe 79 from the supply pipe and also has an outlet port 94 which is connected with that portion of the pipe 79 which extends to the cylinders 19. Within the casing 92 a chamber 95 is formed into which the portv 93 opens and also has formed therein a chamber 96 which opens into the chamber' 95 and into which the outlet port 94 opens. TWithin the chambers 95 and 96 a valve stem 97 is provided which has an end portion 98 slidably mounted in a .recess formed in a plug 99 which plug forms one of the walls of the chamber 95. This member extends into the chamber 96 and beyond the outlet port 94 is provided with an enlarged portion 100 which fits the chamber 96 and is slidable therein. Between the end portion 98 and the portion 100, the valve stem is provided with an enlarged por- -tion or valve 101 which is adapted to seat on a valve seat 102 formed in the chamber 95 to shut off the fluid pressure from the chamber 96. Between the valve 101 and the portion 100 the stem is of considerably smaller diameter than the valve 101 or the portion 100, thus providing suitable space between the stein and the inner surface of the Achamber 96 for the passage of fluid pressure. The end'108 of the stem is of smaller diameter than the chamber 96 and seats in a packing cup 104 which is mounted on the inner end of a valve stem extension 105 and pre- `vents the escape of fluid pressure through the chamber 96 to the atmosphere, the outer end portion being suitablymounted in the casing' 92. The end of this extension engages the inner end of a cut off rod 106 within the casing, the outer end107 of this rod being rounded and' adapted to engage the push rod sleeve 60. It will be noted that the stem is movable forward a sufficient distance to close olf the fluid pressure supply from the chamber 96, and is movable backward a sufficient distance to permit the fluid pressure to enter the chamber 96.

The piston rod sleeve 60, adjacent its lower end has formed therein` a groove 108 in which the end 107 of the cut off rod is adapted to move when the piston rod has been moved upwardly a sufficient predetermined distance to bring the recess opposite the end 107, thus permitting the valve 101 to move to its closed position. lVhen the piston rod moves downwardly the cut off rod Will be engaged by the sleeve 60 and forced inwardly so that the valve 101 will be moved to its full open position, and by such engagement will be held in such position until the piston rod is moved upwardly again a suflicient 'distance for the groove 108 to be opposite the end 107 of the cutoff rod 106.

Between the cut off valve and the cylinders 19 exhaust valves 109 are provided each of which is located adjacentone ofthe cylinders 19. Each of these valveshas a casing 110 in which is formed an inlet port 111 which is connected with the portions ofthe pipe 79 from the port 94 of the cut off valve, an outlet port 112 which is connected with the portions of the pipe 79 which opens into the inlet port 113 ofthe cylinder 19 and has an outlet port- 114 which opens to the atmosphere. Within the casing a chamber 115 is formed and with which the ports 111, 112 and 114 communicate. This chamber is of greater diameter at its upper end than at its lower portion; thus an annular shoulder 116 is formed within the chamber. Movably mounted in t-he chamber is a piston valve member 117 which comprises an upper portion 118 which fits the upper portion` of the chamber and is slidable therein. Integral with this portion and extending downwardly therefrom into the lower portion of the chamber is a port-ion 119 which is for the ,greater portion of its length of smaller diamtion 119 is adapted to seat on a valve seat 121 which surrounds the outlet port 114 and pre.- vents accidental escape of fluid pressure to the atmosphere. The member 117 hasv a recess 122 formed in it-svcentral portion, which communicates with the lower portion of the chamber 115 through the medium of openings 123 which are formed in the portion 119.

The upper end of this recess is restricted in size by a plug 124 having an opening 125 formed therein which communicates with the upper portion of the chamber 115 and the lower surface of the portion 129. The

upper surface of the portion 129 is adapted to engage the lower surface of the plug 124 to prevent the escape of fluid pressure in the recess 122 through the opening 125 in the plug 124. The upper portion 128 of the valve stem extends into the opening 125 and this portion, due to its shape, will permit fluid pressure to enter the recess 122 and will, due to its sliding engagement with the lug 12-1, guide the valve stem member so that there will be no binding act-ion between this portion of the stem and the plug 124.

Assuming the car body to be in its righted and locked position as shown in full lines in Figs. 1 and 6 of the drawings and that it is to be tilted to the left hand side as shown in Figs. 2 and 7, the operation is as follows The operator connects one end of the supply pipe 76 on the right hand side of the l car with a suitable fluid pressure supply source, such as an air reservoir of a locomotive, and then opens the valve 78 adjacent this end of the supply pipe, the valve 78 at the opposite end of the. pipe being closed when a single car is to be operated. When a plurality of cars are to be tilted simultaneously this last referred to valve is opened as are all the valves on the right hand side of the cars with the exception of the one at the end of the last car, which valve is closed to prevent the escape of the fluid pressure. The operator, who may be at one side or the other of the car, moves the member 86 across the car asuliicie-nt distance so that the ports 81 and 82 of the valve 8O will be open, thus permitting the fluid pressure to pass through the valve and pipe 79 into the lower ends of the cylinders 19 located on the right hand side of the car. rlhe fluid pressure enters the cylinders beneath the pistons 39 and forces such pistons and piston rods 38 upwardly. As Vthe piston rods are moved upwardly the parts thereof will move the levers 71 upwardly causing the shaft 41 to rotate in the direction as indicated by t-he arrow in Fig. 9.

As the shaft 41 is moved in this direction the levers 57, at each end of the car body, are moved with it, which causes the locking member to move in the same direction at an increased speed, thus moving the leg 53 of each member out of its locking position with the adjacent locking bar 46. As these levers 57y are rotated with 'the shaft, the lugs 58 of such levers, which are in engagement with the link 42 within the notch 59, will cause the link 42 and locking bar 46 to move upwardlyl until the stop 48 on the locking bar is free of the stop 49 secured to the bolster as shown in Figs. 2, 4 and 5` of the drawings. At this time the bottoms of the slots 44 engage the shaft 41 and a further rotation of the shaft causes the link 42 to rotate in the same direction which causes the bar 46 to move in the direction as indi-v cated by the arrow in Fig. 4, thus pulling the support 28 at each end of the left hand side'of the car, inwardly out of engagement with the corresponding support 35 secured to the body.

As the supports 28 are' moved out of supporting engagement with the members 35 on the left hand side of the car, the upper ends 37 of the piston rods on the right hand side f of the car engage the members 36within the notches and as the pistons continue to move upwardly the car body will be tipped to the left hand side.

As the left hand side of the car body' moves downwardly the lower end portions of the members 36 depending downwardly from this side of the body will engage the surfaces 67 of the portions 61 of the piston rods and will force the portions 61 in a direction toward the longitudinal center line of the carl a suiiicient distance to permit the members 36 to enter the cylinders 19. The portions 61 as they are moved in this direction force the lower portions of the levers 71 on the lefty hand side of the car out of engagement with the parts 60 so that when the'car body is righted, as hereinafter described, the supports 28 on the right hand side of the car will not be movedfrom their supporting positions. It will here be noted that the members 36 are adapted to enter the cylinders 19 and due to this the cylinders can bespaced away from the longitudinal center line ofthe car a greater distance than has heretofore been possible with the resulty that the power from the cylinders is applied more advantageously to the car body, so that the car body is more easily tipped and righted. With this arrangement the cylinders can be placed nearer the bottom of the car bodyl than has heretofore been possible; thus the cylinder can be made longer which will permit of a longer piston travel which is desirable in a car of this type.

In tipping the car the pistons move the j' right hand side of the car upwardly just enough to unbalance the body and when this has been done the body will, due to gravity, complete its tipping movement without the assistance of the pistons. It will, however, be noted that after the car body leaves the piston rods the fluid pressure continues to force the rods upwardly until such time as the groove 108 in the part 60 of one of the piston rods come in line with the cut oft' rod 106 at which time the fluid pressure in the chamber 95 will force the valve stem 97, valve stem extension 105 and cut off rod 106 longitudinally so that the outer end of the cut off rod will move into the groove 108 a sutlicient distance so that the portion 101 ofthe valve stem will engage the valve seat 102 and will shut 0E the supply of fluid pressure to the cylinders before the pistons thereof have moved their maximum distance upwardly; thus any further upward movement of the pistons will be independent of the admission of fluid'pressure thereto, and in this way the vpiston is prevented from striking the cylindercover. The cutting off of the pressure before the piston has reached the cylinder head results in a great saving of fluid pressure.

The operator now moves the member 86 transverselyI of the ear in the direction opposite to that indicated by the arrow in Fig. 13 until the lever 87 of the valve 80 is in the position as shown in dot and dash lines in F ig. 13, at which time the fluid pressure from the supply pipe will be cut 0E and the ports 82 and 83 be connected so that the fluid. between the cylinders and the valve 80 may be exhausted to the atmosphere through the port 83. The pistons and piston rods now move downwardly by gravity and force the fluid baclr through valve 109 and pipe 79. As one of the pistons and piston rods moves downwardly and the end portion of the groove engages the end of the cut off rod, this rod together with the valve stem and valve stem extension are moved back by the part 60 a suliicient distance so that the portion 101 of the valve stem will be moved out of contact with the valve seat 102, thus permitting a portion of the exhaust fluid to pass through the valve 91 to the atmosphere. The valves 109 are for the purpose ofassisty ing in exhausting the fluid from the cylinders and to-thus facilitate the quick return of the pistons and piston rods to their normal positions of rest. l/Vhen the valve is in position to exhaust the fluid pressure and the pistons and piston rods move downwardly the exhaust pressure due to the weight of the pistons and piston rods will not all pass through the openings 122 in the portions 118of the piston valve members 117 to the atmosphere through the port 83 of the valve 80 and the pressure which does not pass through these openings will raise the piston valves 117 from their seats, thus opening the port 114 to the atmosphere which permits the rapid discharge of the pressure from t-he cylinders through this port.

As the pistons and piston rods reach their normalV positions of rest the ends of the levers 71 on the right hand side of the car will again seat on the upper portion of the part 60 oi the piston rod. After the pistons and piston rods have moved to their normal positions of rest the operator, by the use of the member 86, moves 'the valve plug of the valve 80 to its shut olf` position. A

To right the car body and to lock `it in its righted position the operation is as follows The operator connects one end of the supply pipe 70 on the leftY hand side of thel car with the fluid pressure supply source and then opens the valve 7 8V adjacent this end of the supply pipe, the valve at the opposite end of this pipe being closed when a single car is to be righted. rlhe operator, who may be at one side-of thecar or the other, moves the member afsulficient distance so that the ports 81 and 82 of the valve 80 at this side of the car will open, thus permit-k ting the fluid pressure to pass through the valve and pipe 79 into the cylinders 1-9 on the left hand side of the car which causes car floor and remainin such engagement` until the car is righted.

As the car body is being righted the supports 28 will, due to the weighted portions 32, have a tendency to move outwardly by gravity to their normal support-ing positions and as the body reaches its righted position these members will move underthe members 35 and the stop 48` on the locking bar vwill move into locking engagement with the stop 49 secured to the bolster. As the locking bar is thus moved the shaft 41 will be rotated in the direction opposite to that indicated by the arrow in Fig. 9 that theA leg 53 will again be brought into locking position with the locking bar 46. Y f

The operator now releases the fluid pressure from the cylinders on the left hand side of the car in the same manner as hereinbefore described permitting the pistons and piston rods to return to their normal positions of rest. As the pistons and piston rods return to their normal positions of rest the levers 71 on the left hand side of the car will again seat on the upper portions of the sleeves 60 of the piston rods. Y
